BRUSHING MACHINE.

Application fi1ed February2 6 1923. Serial No 621,256. 7

This invention relates to; what may be termed abrand brusher.

It is customary in the manufacture of cercain. devices such as storagebatteries, to 5 burn by means of a heated die the brand or trademarkinto battery boxes which are generally made of wood. Generally alsothe lines or grooves of the brand burned into the box are painted sothat they wrll stand 10 out sharply or be readily seen This makes itnecessary or desirable that the brand be brushed or freed of the carbonor charred wood produced inthe branding operation.

by the heated die. Heretofore the boxesbrandedin this manner have beenfreed or cleared of the carbon by'bru'shing the boxes .manually with. abrush. I a

The object of the present inventron 1s to provide a machine throughwhlchthe branded boxes may be passed at a rapid rate and which willwhile the boxes are traveling through the machine entirely clear orbrush free of the. boxes the carbon thatadheres to the boxes at;tl1ebrand. 7 V I A still further object is to Provide a machine whichwill accomplish thiswork in a rapid as well as satisfactory mannersoi-that l charred wood I ut1l1ze 1n this instance two rapidly rotatingcylindrical brushes 18, preferably wire brusheswhich are disposed at anangle to each other, as clearly {shown in Figs; 2 and 3 andare'supported beneath the horizontal platform 11 over which the theoperation may be performed inexpensivelyas compared with the handbrushing method used heretofore. p I

' The invention may be briefly summarized asconsisting'in certain novelarrangements and combinations of parts which will be described in thespecification and set for'th'in the appended claims.

1 1 form over and in contact with the brushes Referring now to thedrawings, the ma chine includes a frame or bed 10, which in thisinstance is formed of castings ,but which and Fig 5 is an end view.

may be otherwise formed-if, desired, there being, however, a main frameportion .WlllCll supports thema or portionof the operating mechanisnrNear the top: of the machine there 1S a horizontal elongated platform 11along which the battery boxes to be placed on the In the accompanyingsheets of drawings,

brushed are moved, one of these boxes being shown at B in Fig 1. At thesides of this platform 11 are upstanding guides 12 having inwardlyfacing flanges on the lower of which the platforinll is supported. Theseguides or channels 12 are supported from the bed or frame membersbeneath by brackets 13, as-shown in Figs. land 4.

The battery boxes orother parts to be brushed, are placed on one end ofthe platform 11 and they are moved along the platform by an endlessconveyor consisting of endless side/chains 14 which engage end sprockets'15, and cross bars 16 which connect the side chains, one of these crossbars being best shown in F ig.4. Preferably the upper portions of thechains between the end sprockets 15 slide over the inwardl 'ex tendedhorizontal flanges ofangles '1 secured to the inner sidesof the channels-12, asfbest shown in ig. 4. In the embodiment of the invention hereshown, the lower sides of the boxes as they aremoved along the platformare subjected to a brushing operation, and therefore the boxes will beplatform with the branded; sides downward. i

To brush the brands'free of carbon or boxes are moved bythe'conveyor,the plat I form being provided with a pair ofproperly d.isposedslots '19(see Fig. 2) t-hroughwhich the upper portionsof the two brushes pro-]ect'. Itmay be here'stated that by thense of t 'wo b'rushesdiagonally'disposed and rotated in opposite directions as will beexplained subsequently. the brush bristles will I be. able to 'enter andthoroughly clean all parts of the depression being cleaned. v.VVhen theboxes are moved along the plat- IS -they are definitely positionedwithredownward by adepressor consistingof a frame 23 supported byupstanding brackets 24: mounted on the side channels 12. This depressor,which is gravity actuated and by its weight .holds the boxes downagainst the" brushes; preferably consists of a pair of V angles 23connected together by a pair of elevated by the next battery box. i n'lig. 1, the guides 2 1 of the upright brackets 2a on which the rollers 23act, are

cross pins or bars 23 provided at theirends with rollers 23 (see Fig. l)which engage guidegrooves or surfr zces2l in the upright brackets 24.

As best shown in Fi 1. the an les 23 of ca O the depressor 23 areprovided with straight and no -mally horizontal middle portions andingwardly inclined ends. The inclined ends towards which the batteryboxes are approaching are preferably straight, while the opposite endsare preferably curved, as shown n Fig. 1. The actionis as follows: Thebattery boxes are moved along the horizontal guide 21 towarcs the slots19 in the platform llthrough which the brushes pr01ect, vand when theycome under the upwardly nclined ends of the angles 23 of the frombeneath the depressing .f.1;'ame which is then lowered or in positiontobe acted on or As shown curved as shown at as in Fig. l, the curva---ture of the two guides being such that the frame 23 may readily tiltupward at one end while the battery box slides under the frameand thenpass beneath the frame by allowlng the cndwhlch was first elevated tobelo vered, and finally the curved end to be lowered, toltheaositionshown in Fi 1.

That is tov say, the frame first tilted up at one end and then assumesan upperhorizontal positiomon thebox and stays "in thatposition andvpressesithe box down while it is being brushed. and then the forwardend which was first-elevatedis lowered, and then the rear'end drops,down' to the position shown. V I v I V For the purpose of rotating thebrushes 7 at high speed and also operatingthe conveyor, I utilizea'motor 25 which is support-- ed on the frame .or body member 10 Theshaft of the motor has a pinion 26 which engages a pinion 2.7 on a shaft28 having bevel gear 29 and behind the bevel gear a spur gear 29? notshown. The spur gear drives a gear 30011 a shaft 31 having asprocketwheel 32 which by means of a sprocket chain 33 drivestheconveyor.

The bevel gear 29 engages a bevel gear 34 on a vertical shaft 35extending upward along onesiderof the frame. At the top of "the verticalshaft 35 is a bevel gear 36 enadjustment takes place.

gaging a bevel gear 37 onthe shaft 38 of one of the brushes 18, as showninlligs. 1 and 3. l hus one of the brushes 1s drlven, and

it in turn drives the other brush through bevel'gearing 39 at thefariend of the two brushes where the shafts are achacent each Qtherasshown in F 1g. 3. This arrangement causes the brushes to rotate inopposite lirections.

. It is highly desirable that the pressure of thebrushes against theboxes be made adjustableor variable, and therefore in accordance withmy'invention the brushes can be .raised or lowered without- (disturbingthe .drlve above described. 'Tobring'this about,

theshafts of the two brushes at 'their'adjacent ends are supported inbearings 10, and at their ends which are relatively far apart theyaresupported in bearings ll the'bear ings 40 and 41 beingcarried by ahorizontal plate 42 which is adapted to beraised and lowered. v Thisplate 42, which .is shown in both'Figs. 3 and 4,-is supported from afixed horizontal plate 43, beneath it through the medium of a series ofscrews 44;, the plated?) being supported on the frame of body member 10.The upper ends of the screws i l extend freely into sockets .of theupper plate L2, but-their lower portions are threaded and engage inthreaded openings ofthe lower plate l3. It will beseen, therefore, thatit will only be necessary to turn these screws so as to raise or lowerthem to raise or lower the plate 42 and the brushes 18. To bringth'isabout the middlefport-ions of the screws are provided withpinions4E5 (see Figs. 3

and f) which pinions are engaged by a gear l6"jou rnaled on a centralvertical stud 47- of the lower plate 43, this gear 46 carrying 'onitsunder side a bevelgear 4 8 engaged by a bevel pinion t'9 on a horizontalshaft150' which-projects out from theside of the machine and is providedwith an adjusting hand wheel '51,

, Therefore, if to bring about thedesired results a more severe brushingactionis desired, the operator will turn the hand'wheel blso' asto'elevat'e the brushes, or i-fa less severe brushing action is desired,the operator will-turn the hand wheel so as tolower the brushes. 1 7

In order that theelevation of'the brushes maybe varied by turning thehand wheel 51, i

one of the bevel gears on the shaft 35, preferably the lower gear 34 issupported independs ently of the shaft '35,and the shaft has a splinedor sliding :connection with this bevel gear so that the distance betweenthe lower and upper bevel gears 36 may'vary as the Having described myinventiorn'l claim: 1. Ina machine of the character described, aplatform along which the articles to be brushed ,are .moved, a brushprojecting through the platform, and a vertically mov-' able gravityactuated depressorunder which the articles move and which serves toholdof said platform and having an inclined forward end. a

3. In a machine of the character described,

a platform along which the articles to be brushed are moved, a brushprojecting through the platform, and a vertically movable gravityactuated depressor under which the articles move and which serves tohold I the articles down against the brush during the brushingoperatlon, said depressor being supported at opposite sides of saidplatform and havin straight mi dle portion.

,4. In a machine of the character-described,

members provided with a a platform along which articles to be brushedare moved, a rotating 7 brush projecting through the platform andadapted to contact with the entire under surface of the article beingbrushed, a, yielding depressor under which the articles move, and meansextending along the platform for definitely positioning the articlesrelative to the depressor as they move under the same.

In testimony whereof, I hereunto aflix my signature. r
